This invention mlates to improvements in coWl ventilators for motorvehicles. I

One object of the invention is to provide improvedmea-ns for ventilating'a motor vehicle, comprising a ventilating opening in the cowl thereofand a cover for said open-.

ing, together with improved means for oper ating, the cowl from a pointadjacentthe drivers seat. 1 r i A further object of the. invention is toprovide simple and efficient means for-operating the cowl ventilator,said mean'sibeing readily actuated and ofsuch a. nature" as toresiliently hold the cover for the ventilator opening either in open: orclosed position;

A further object ofthe invention is to provide a device of thischaracterivvhich is of simple constructionand eflicient in opera-Further objectsof the invention relate to economies of manufactureand'detai'ls' of construction as will l'iereinafter appear 'from thedetailed description to follow, i The objects of the invent'onfareaccoin plished. in one instanceiby the devices means described {inthe following specific? tion but it is evident that the same may bescope of the'invention' as pointed out in the appended claims.

In;,this way, the desired degree of tension instance, and the tension ofthe spring may i be regulated later as is found necessary. The

bracket20is, so positioned relative to the bracket '10 that thealignedbearings 23 and 24;;Carried by the bracket 20 are located ad acent theoffset portion Hof the bracket 10 j and in line the'rewith. Anactuatingrod 25' is adapted to be mounted within the aligned bearings 23 audit,and has one end portion thereof projecting through the instrument board3 whereby therod 25 is capable of being' rotated from a point adjacentthe drivers seat. Thebearing23 is provided with an internal thread 26for co-operation with an external thread 27 formed uponone end portionof the operating rod whereby upon rotation oflthe rodthe same 1s movedin an axial direction into engagementwith the offset portion 16Lofthe'bracketlO. for rotating the bracketlOabout the rod. 6 as an axisand thus raising or loweringthe cover 9,

' I end portion of the operating rod 25 which is locatejd'a'djacent thedriverls seat is provided 7 with ahandle 30 whereby the operating rod iscapableof being readily rotatedto raise or lower the cover.

. ltwill be understood from the preceding description that whenftheoperating rod 25 isrotated in one direction the end portion of vthe'rodlocated'adjacent the bracketlO will bear against the offset portion 14of the bracket'andgupon continued rotation ofthe rod the cover 9 will beraised against the tension exerted by the coil spring 15. hen

the operating rod is rotated in the opposite direction, the endpoi'tionof. the rod which n is adapted to bear against the offsetportion 140ithe bracket will be drawn inwardly and the cover permitted toreturn toits nor mally closed position under the influence of the coil spring 15.It will, be seen from the above description that. a particularly simple.and'efficient formof-cowl ventilator is pro vided wherein the variousoperating parts are of simple construction and capable of be ing readilyand easily assembled. -Moreover,

, the coil spring.

The

the structure is capable of being readily and easily operated forraisingand lowering the cover, and may be readily adjusted whereby thecover is constantly maintained in any of its desired pantie-11s.
